![]() This approach provides all the benefits of having all your data inside of database, including ability to ensure transactional consistency (meaning that BLOB data stored it the database subject to all database constraints you defined) and simplified management. Prior to availability of SQL Server FILESTREAM feature possible answers to the problem described above were:ġ) Storing data in table storage/VARBINARY(MAX) columns. But let’s look at what we had before first. SQL Server FILESTREAM is one of the technologies allowing you to do this. This requirement drove search for ways of joining those two disparate data silos into one or at least connecting them in some way. Although file system serves well for storing files, it lacks in management capabilities if compared with those provided by DBMS and potentially leaves your business data in two disconnected silos: database and file system. Historically, there was no way of storing these files or, in other terminology, BLOBs ( binary large objects) in SQL Server database. Depending on business, these files can be anything from scanned originals of legal documents to audio, video, drawings or any other possible proprietary file format which stores data you need. You have some of these features with modern file system level storage, but DBMS capabilities are richer.įrequent business requirement you may encounter is requirement to store some large files so that they are linked/associated with all other business information which is stored in your LOB ( line of business) database. Main benefit of any DBMS is an ability to store data in a structured way facilitating information retrieval combined with capabilities to manage your data, ensuring that you have such things as backups and security controls which can be applied on the level of one management entity – database. In this article I want to talk about SQL Server FILESTREAM feature making sure that both parts are covered. ![]() First, you need to understand its intended use case, and second you need to understand how to use/implement this technology in practice (and, for your own good, you should do it strictly in that order). When it comes to familiarizing yourself with any new technology there are always two parts. StarWind Virtual Tape Library (VTL) OEM.
